IPv6 addresses are longer than IPv4 addresses, and are so capable of greater expression. Given an IPv6 address, conventions and standards allow us to draw conclusions about how IPv6 is being used on the node with that address. We show a technique for analysing IPv6 addresses and apply it to a number of datasets. The datasets include addresses seen at a busy mirror server, at an IPv6enabled TLD ...

Aiming at the issues of smooth transition from IPv4 to IPv6 and interoperability in technical coexistence period about campus network, discussing the technical characteristics of IPv6 protocol, GNS3 and OPNET simulator, combined with the status of weakness of IPv6 technology , lack of IPv6 technology planning and financial support for network upgrade in the vast majority of colleges, adopted th...

There is growing operational awareness of the challenges in securely operating IPv6 networks. Through a measurement study of 520,000 dual-stack servers and 25,000 dual-stack routers, we examine the extent to which security policy codified in IPv4 has also been deployed in IPv6. We find several high-value target applications with a comparatively open security policy in IPv6 including: (i) SSH, T...

This paper highlights the need to supplement the work within the IPv6 community on IPv6 management with mechanisms specifically to support IPv6 transitioning. As a major feature of any IPv6 network for the considerable future, management support for the deployment and operation of a transitioning infrastructure is vital. We will propose a format for transitioning management information and exam...

The Dynamic Host Configuration Protocol for IPv6 (DHCP) enables DHCP servers to pass configuration parameters such as IPv6 network addresses to IPv6 nodes. It offers the capability of automatic allocation of reusable network addresses and additional configuration flexibility. This protocol is a stateful counterpart to "IPv6 Droms (ed.), et al. Expires 1 Aug 2002 [Page i] Internet Draft DHCP for...

The Dynamic Host Configuration Protocol for IPv6 (DHCP) enables DHCP servers to pass configuration parameters such as IPv6 network addresses to IPv6 nodes. It offers the capability of automatic allocation of reusable network addresses and additional configuration flexibility. This protocol is a stateful counterpart to "IPv6 Stateless Address Autoconfiguration" [13], and can be used separately o...

This paper presents a secure authentication method for Mobile IPv6. As a default IPsec is used for secure signaling messages between the Mobile Node and other agents in Mobile IPv6 networks. Mobile IPv6 message transactions include the Binding Updates and Acknowledgement messages as well. We propose a new mechanism for securing Mobile IPv6 signaling between Mobile Node and other agents. The pro...

Abstract. Dual Stack Mobile IPv6 (DSMIPv6) is an extension of Mobile IPv6 to support IPv4 care-of address and to carry IPv4 traffic via bi-directional tunnels between mobile nodes and their home agents. Using DSMIPv6, mobile nodes only need the Mobile IPv6 protocol to manage mobility while moving within both the IPv4 and IPv6 Internet. This is an important feature for IPv6 mobility during its d...

Mobile IPv6 signaling between a Mobile Node (MN) and its Home Agent (HA) is secured using IPsec. The security association (SA) between an MN and the HA is established using Internet Key Exchange Protocol (IKE) version 1 or 2. The security model specified for Mobile IPv6, which relies on IKE/IPsec, requires interaction between the Mobile IPv6 protocol component and the IKE/IPsec module of the IP...

IPv6 rapid deployment on IPv4 infrastructures (6rd) builds upon mechanisms of 6to4 to enable a service provider to rapidly deploy IPv6 unicast service to IPv4 sites to which it provides customer premise equipment. Like 6to4, it utilizes stateless IPv6 in IPv4 encapsulation in order to transit IPv4-only network infrastructure. Unlike 6to4, a 6rd service provider uses an IPv6 prefix of its own in...
